Scientists develop novel technique to grow meat in the lab using magnetic field

Posted by in categories: bioengineering, biotech/medical, genetics

Scientist from the National University of Singapore (NUS) have found a novel way of growing cell-based meat by zapping animal cells with a magnet. This new technique simplifies the production process of cell-based meat by reducing reliance on animal products, and it is also greener, cleaner, safer and more cost-effective.

Cultured is an alternative to animal farming with advantages such as reducing and the risk of transmitting diseases in animals. However, the current method of producing cultured meat involves using other , which largely defeats the purpose, or drugs to stimulate the growth of the meat.

To cultivate cell-based meat, are fed animal serum—usually fetal bovine serum (FBS), which is a mixture harvested from the blood of fetuses excised from pregnant cows slaughtered in the dairy or meat industries—to help them grow and proliferate. This is a critical, yet cruel and expensive, step in the current cell-based meat production process. Ironically, many of these molecules come from the muscles within the slaughtered animal, but scientists did not know how to stimulate their release in production scale bioreactors. Other methods to promote are using drugs or relying on genetic engineering.
